Description
Woodward LS521
Technical Specifications
- Series: LS500 Series.
- Function: Auto-synchronization and sync-check.
- Voltage Rating: Compatible with low and medium voltage systems via VTs.
Functional Features
- Dual Mode Operation: Supports both auto-sync and manual sync-check.
- Load Sharing Interface: Communicates load data to the controller.
- Event Recording: Logs sync events for troubleshooting.
Application Scenarios
Widely used in standby power systems, prime power plants, and islanded microgrids.
Performance Parameters
- Accuracy: High-resolution measurement for stable paralleling.
- Reliability: Proven track record in continuous operation.
Material Composition
Industrial-grade PCB with protective conformal coating.
Structural Characteristics
Modular design for easy replacement and expansion.
Working Principle
Continuously compares generator and bus waveforms. When the slip frequency and phase difference are within safe limits, it initiates the breaker close sequence.
Installation Requirements
Connect VT and CT circuits with correct polarity. Verify breaker control voltage matches module ratings.
Precautions for Use
Ensure proper isolation of measurement circuits. Perform primary injection testing to validate sync logic.
